Black Utility Blades - 9mm (10 Pack)

Green Stuff World Premium Black Carbon Steel Utility Blades - 9mm (10-Pack)

Keep your workshop cutting tools performing at their absolute peak. This 10-pack of heavy-duty, 9mm utility knife refills is engineered from high-grade BLACK SK5 carbon steel, delivering long-lasting performance, deep precise cutting, and maximum mechanical control.

Designed to seamlessly fit the Green Stuff World ComfortGrip Utility Knife, as well as any standard 9mm snap-off utility knife on your workbench.

Why Black SK5 Blades Are Superior for Makers:

• Heavy-Duty Structural Slicing: Perfect for clean-up work, removing thick support material, trimming raw 3D prints, and shaping dense modeling foam.
• Extended Blade Longevity: High-grade black carbon steel goes through a specialized hardening process, allowing it to maintain an ultra-sharp edge up to 3x longer than generic silver steel blades when slicing through abrasive plastics (PLA, PETG, ABS).
• Precise Snap-Off Segments: Features crisp score lines along each 9mm blade, allowing you to instantly snap off a dull tip and reveal a fresh, razor-sharp edge in seconds.

Specifications:

• Blade Width: 9 mm
• Thickness: 0.4 mm (0.04 in)
• Material: Premium Hardened Black SK5 Carbon Steel
• Quantity: 10 heavy-duty blade refills per pack (housed in a protective plastic storage case)

Together, Layer by Layer!
